DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hairdressing brush, and more particularly, to a hairdressing brush which is molded from an antistatic material and is used for hairdressing in combination with a drier or the like, which is generally called a "skeleton brush". .

[0002]

2. Description of the Related Art In recent years, hair styling brushes called "skeleton brushes" formed so as to easily pass hot or cold air from a dryer have been put on the market. In general, a skeleton brush is formed by integrally molding a brush bristle fixing portion in which a large number of brush bristles are arrayed and fixed on a surface, and a grip portion extending from the brush bristle fixing portion.
The stem is composed of a stem (stem) extending coaxially with the grip and extending from the distal side of the grip, and a branch that branches from the stem to the left and right on substantially the same plane. The brush bristles protrude from the surface side of the stem portion and the branch portion at right angles or at a predetermined angle.

[0003] When used with a dryer, for example, the hair that has been combed is blown with a dryer while adjusting the flow of hair between the brush hairs, and the hair is blown on the surface of the brush hair fixing portion or on the back surface. And perform styling (shaping). At this time, since the air blows through from between the branches, it is possible to effectively blow air to the hair portion where styling is to be performed.

On the other hand, it is conceivable to form the entire skeleton brush with a conductive material in order to prevent static electricity, for example, to suppress the generation of static electricity between the head hair and the brush hair or to ground the generated static electricity.

[0005]

The stem portion and the branch portion described above are apt to be broken or broken because both of them are formed of relatively elongated rod-shaped or plate-shaped molded portions. On the other hand, if the skeleton brush is molded from a conductive resin or a conductive resin capable of providing effective grounding, the material cost is increased as compared with the use of a general-purpose resin. In addition, in order to maintain a predetermined strength over the entirety including the grip portion, it is necessary to design a sufficient amount of a resin used as a material, and if a sufficient amount of the resin is not used, rigidity cannot be obtained. The stability of the brush operation during use is impaired.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an inexpensive hairdressing brush which has both conductivity and strength and is formed so as to be easily blown by a dryer. Is to provide.

[0007]

According to the present invention, a brush bristle array made of a conductive material having a large number of brush bristles arranged and fixed integrally on its surface, and a gripper made of a non-conductive material, The array body and the gripper had a plurality of common ventilation through holes, and further provided a fitting pair that fits each other and joins the back surface of the brush bristle array body to the distal surface of the gripper. A hairdressing brush is provided.

That is, according to the present invention, a plurality of common through-holes are formed, and a gripping member made of a non-conductive material and a brush bristle array made of a conductive material are joined by a fitting pair to thereby form a conductive material. Can be limited to only the brush bristle array body, and the brush bristle array body and the holding body joined by the fitting pair can be fixed with the same strength as that of the integral molding.

The conductive material in the present invention refers to a conductive material capable of effectively grounding static electricity generated between the head hair and the brush hair through the grip portion, and specifically, a conductive resin. Alternatively, a composite conductive resin in which a conductive filler is dispersed in a polymer may be used. The non-conductive material in the present invention is preferably a general-purpose plastic which has a relatively large amount of circulation in the market, is inexpensive and has good moldability, and its conductivity value does not matter in the present invention. Specific examples include polypropylene (PP), polyethylene (PE),
Examples include polyacetal (POM), ABS resin and AS resin.

[0010] The fitting pair is constituted by a concave groove formed along the peripheral edge of the back surface of the brush bristle array body, and a ridge formed on the gripping body and fitted into the concave groove, or a combination thereof. Conversely, there is a brush bristle array formed by a ridge formed along the periphery of the back surface and a groove formed on the gripper and fitted to the ridge. These grooves and ridges may be formed continuously or intermittently. Further, the present invention also includes a fitting pair in which both the groove and the ridge are formed in both the brush bristle array body and the gripping body.

The brush bristle array body and the gripping body further have an annular protruding portion projecting from the opening edge of one of the through holes at a substantially right angle, and being fitted to the inner peripheral surface of the other through hole. The joining surface between the brush bristle array and the gripping body increases, and more firm bonding can be performed, and the displacement of the through hole between the brush bristle array and the gripping body can be prevented. By providing the brush bristle array with the grounding protrusion protruding to the proximal side of the gripping body, a part of the human body, for example, a fingertip can easily contact the brush bristle array via the grounding protrusion, and more. Reliable grounding is possible. If the brush bristle array body and the gripping body are fixed by heat fusion or an adhesive, they are more firmly joined.

And open both sides.

The proximal side of the grip body 3 is a grip body 35 having a narrow width from the joint surface portion 30 and extending with a constant width in a direction coaxial with the joint surface portion 30. A distal side of the surface of the grip body 35 has a semicircular step 37 corresponding to the shape of the grounding protruding portion 25 formed at the proximal end of the brush bristle array 2.
And is configured to be in close contact with the brush bristle array 2.

When the brush bristle array 2 is joined to the joint surface 30 of the gripping body 3 in assembling the skeleton brush 10, first, the positioning concave portion 22 and the positioning convex portion 3 are used.
2 and the positioning is performed, and then the concave groove 21 of the brush bristle array body 2 and the convex ridge 31 are fitted. At the same time, the annular projection 34 is fitted into the fixed plate through hole 23. As a result, the end surfaces 26 and 36 are flush with each other without displacement, and the outer peripheral surface of the annular projecting portion 34 is in close contact with the inner peripheral surface of the fixed plate through-hole 23, so that a firm fixing is performed. The assembled skeleton brush 10 is shown in FIGS.

Skeleton brush 10 with dryer
When using the hair, the combed hair is blown with a dryer while adjusting the flow of the hair between the brush hairs 11, and is blown on the front surface 2 a of the brush hair array 2 or the back surface 3 of the gripping body 3.
The hair is wrapped around b as well for styling. At this time,
Since the air blows through the through-hole portion of the joint surface portion 30, the air can be effectively blown to the hair portion to be styled.

Since the brush bristle array body 2 has a protruding portion 25 for grounding on the proximal side and protrudes to the proximal side of the gripping body 3, the part of the hand gripping the gripping body 3, for example, the fingertip, is electrically conductive. It is easy to contact the brush bristle array 2 made of resin, and a reliable and effective grounding can be performed. Therefore, the brush bristles are made more satisfactorily to suppress split ends and cut hairs. The skeleton brush 10 is composed of the brush bristle array 2 including a grounding projection 25 made of a conductive resin and the holding body 3 made of a non-conductive resin. It can be molded from a smaller amount of conductive resin material than a molded product. Furthermore, since effective grounding can be performed, an increase in material cost can be suppressed. This makes it possible to sufficiently use a general-purpose resin having a low material unit price, and to easily maintain the strength of the entirety including the grip portion.

Embodiment 2 FIG. 2 shows a hairdressing brush according to another embodiment of the present invention. Skeleton brush 5 as a hairdressing brush
